Been building a bit, can't progress until the new rotor for my 40mm edf arrives from AEO im testing the new 7 blade rotor as it gives 190g of thrust on 2s at 14A and 225g of thrust on 3s at 18A just need to add the topskin and bottom skin and then its into the canopy but i can't do anything until the rotor arrives from AEO

Sorry for the slow reply, been very busy.
Keenan,
Looks good, that's going to have some power. How much do you think it will weigh? I'm using a hacker 6100 kv gws stock fan, and getting 145 grams thrust. The auw is 150 grams with thunder power 480mha 3s. Not 1to 1 but it will fly it..
T-spin,
So sorry for the slow reply will try and do better.

I will have the f-35s and f-22 at e fest.
mkcp40 Yeah, on 3 s she really come alive in glad to see your having success with it have you tried the yaw cone yet?
Hope to test fly 40 mm soon and give report.

I hope for it to come in at around 170g rtf but the high thrust is only there becaues of the 1850kv motor which eplains the amp draw

Hello all - I was just turned onto this thread a week or two ago and have been studying these plans. Thanks so much to Au117 for putting the plans out for what looks like a pretty spectacular model!

I also just acquired the GP F86 that I have yet to maiden. I have been planning to build this F35 as a recipient for the F86 guts once I smash it beyond repair. However, I think I already have pretty much everything needed for this plane except a fan/motor/esc combo, so I thought I might go on and give it a shot. Would this one work well with this plane? I'd pair it with a 12A ESC, so there is a little pad on the amps. Past that I've got a DSM2 knock off Rx and a handful of 4g and 5g servos all powered by a 2S 330mah 25C lipo. I'd be going for the 'C' version just to lower the wing loading a little bit (I have a pretty tight flying area).

This F86 is my first EDF model, so this is all new territory for me. TIA for the help.

p.s. After looking at this, it seems that this gear is a bit big/heavy, I think I'd have a hard time keeping the weight in control. What about this smaller EDF unit? A little lighter on the motor, and a little bit less amp draw, so I could get away with a little smaller ESC and probably the smaller, 220mah battery. Still seems like it'd have about a 1:1 thrust to weight ratio.

How small of servos do you think you could put on this model? I'm wondering if I could use the little 2.5g or 3g sized ones. How big are the stock GP F86 ones? This is one of my complaints about the F86, no access to the equipment!!!

Reason: Thought about it a little more...

Thanks DJ. I couldn't help myself, so I just went on and ordered a whole new set up... imagine that!

I ended up ordering a 27mm fan from BP Hobbies. 10,000kv motor and 7 blade rotor. I also ordered a Proton 6A ESC and some 2.5g servos from Hobbypartz. The system will be powered by a 2S 220mah 25C battery from RCPlaneBuilder. This'll be a fun experiment into micro EDFs, I can't wait to get started!

Led,
I've flown my 53g F-35C with HK's version of the 27mm fan you described and I've also flown the stock GP Micro Sabre. There's no comparison...the Sabre with GP's 30mm Hyperflow system has way more power (same 180mah 2S batteries for the comparison) and is a lot more fun to fly!
I've started my second F-35C with (you guessed it) 30mm GP Hyperflow EDF. Will report when I fly version 2.

Thanks for the note Bill. I have read some mixed reviews on this 27mm fan... I'm curious if the one I've ordered from BP is the same one. The fan and rotor certainly look exactly like the HK one, but the motor is listed with different specs. If it gets anywhere close to what they have listed (72g static thrust on 8.4V at 4.9A and 66g static thrust on 8.0V at 4.6A) it ought to move this little bird at a pretty good clip!

I'll look forward to hearing how your second F35 turns out, good luck!

The Hyperflow on a good 3S 180mah pack will increase the factor even more.

Have started my second F-35C following au117's plans. Using the EDF above and a bit puzzled...although there's a stator ring, there's really no "shroud" . Am I missing something? I can't find anything on GP's website to indicate there should be a traditional shroud.
